For 61 for instance. Do I take 3kN X4 then divide by 2. Then place that value at 1/3 of 4m??
OR do you take 3kN and X by the entire thing 12m and place that value at 1m. THEN difference of 7 and 3 is 4X6 all divided by 2 for the force. Then place that value at 1/3 of 6, plus the 4m at the beginning when taking the moment from A.
Does that make sense. the last one would be the difference still of 4 X 2, which is 8 at the 11m mark??
